PERHAPS A CALL TO THE MANUFACTURER AND THEIR TECH SUPPORT PEOPLE WOULD GIVE YOU A BETTER IDEA WHAT CAN BE DONE . THINGS THAT HAVE POWER RESTRICTIONS DO NOT LIKE HAVING MORE THAN THEY WERE DESIGNED FOR PUT THRU THE SYSTEM . PERHAPS A BIGGER RESISTER WOULD FIX IT

Most often this unit goes dead because of zener diode ZD3 shorting. It is a 18v zener. replace this and you should be back in business.

I don't know if you will see this or not, your post was 2 years ago. I have the same problem. My volume is stuck at 24. I have tried soft-reset........among other things. One thread says to turn volume down to 00 then press for 10 seconds. I have no control over the volume, so, yeah, thanks for that fix. I found that I could get the volume down by unplugging it,plugging it back in and sometimes the volume would pop up and I could turn it down one notch. I did it till I got to 00.............thought AHA! My problem is solved! No such luck. When I press the volume at 00 and try to hold it for 10 seconds, after 3-5 seconds it just pops back to the station frequency. I also thought that if I could get into the guts and spray the volume control with tuner-cleaner, it might help. No go.......after taking off the cover, I found a bunch of REALLY delicate looking electrical tapes and wires..........I was scared I would destroy something in an attempt to reach the volume control. I hate to trash this radio, the sound is awesome...............great design on the speaker, NASTY design on the controls. I'd be VERY interested to know if anyone, anywhere, has found a fix for this. I think maybe my next step will be hitting it with a hammer.
